1.neper官网：Neper: Polycrystal Generation and Meshing — Neper 4.7.0 documentation

2.安装GSL和NLOPT两个软件

GSL：下载地址：http://mirrors.ustc.edu.cn/gnu/gsl/

        安装：(1) sudo ./configure (2)sudo make (3)sudo make install

 NLOPT: sudo apt-get install libnlopt.dev

3.进入neper文件的src文件中：

        a. 安装OpanMP: sudo apt-get install mpich

        b. mkdir Bulid

        c. cd Build

        d. cmake ..

        e. make

        f .sudo make install

4. 安装Gmsh: sudo apt-get install libgmsh-dev

5. 安装Pov-ray : sudo apt-get install povray

6.添加依赖：sudo apt-get install libnlopt0

现在就可以执行命令生成多晶结构了，但是在划分网格时会报错，所以还需要进一步安装Gmsh。

Installing Gmsh

We download the source code from the website 需要搭梯子(https://gmsh.info ), latest version. It is then a good idea to move it to ~/Progs, where Neper already is:

mv gmsh-4.11.1-source.tgz ~/Progs/

tar -zxf gmsh-4.11.1-source.tgz

cd ~/Progs/gmsh-4.11.1-source

We can then compile it. As Gmsh is also managed with CMake, installation is no much different from that of Neper itself:

mkdir build
cd build
cmake ..

-- Build files have been written to: /home/rquey/Progs/gmsh-4.11.1-source/build

Configuration completed and is sufficient for Neper. So, we can make and install:

make
sudo make install

The second command copies the gmsh binary file to a system location, which makes the command available to Neper.

Back to Neper’s build directory, we re-run the tests:

cd ~/Progs/neper-4.6.1/src/build
ctest

99% tests passed, 2 tests failed out of 461

Total Test time (real) =  47.92 sec

The following tests FAILED:
        211 - V/asymptote (Failed)
        325 - V/povray (Failed)
Errors while running CTest

All “M” tests now pass.

现在执行以下命令测试一下效果吧：

neper -T -n 100

neper -V n100-id1.tess -print img1

neper -M n100-id1.tess

neper -V n100-id1.tess,n100-id1.msh -print img2
